This is an Original Two Channel Power Amp from the Early 80s 25 Watts (first 11 Watts Class A) I have the Circuit Diagrams Parts List and Diagnostic Lists. there is a problem with 1 Channel which fades, diagnostics state its most likely a Polyester Capacitor, I just dont have the Heart to play with this at present. 100 Pounds Sterling will Buy it (Shipping is extra) and I'm in the UK
